Gholam Reza Rezaei; Tahereh Binazadeh; Behrouz Safarinejadian

Volume 4, Issue 2 , Summer and Autumn 2016, , Pages 177-184


  This paper considers solving optimization problem for linear discrete time systems such that closed-loop discrete-time system is positive (i.e., all of its state variables have non-negative values) and also finite-time stable. For this purpose, by considering a quadratic cost function, an optimal controller ...  Read More

2. Robust Adaptive Attitude Stabilization of a Fighter Aircraft in the Presence of Input Constraints

M. Bahmani; T. Binazadeh

Volume 4, Issue 2 , Summer and Autumn 2016, , Pages 149-155


  The problem of attitude stabilization of a fighter aircraft is investigated in this paper. The practical aspects of a real physical system like existence of external disturbance with unknown upper bound and actuator saturation are considered in the process of controller design of this aircraft. In order ...  Read More

3. Passivity-Based Stability Analysis and Robust Practical Stabilization of Nonlinear Affine Systems with Non-vanishing Perturbations

H. Chenarani; T. Binazadeh

Volume 4, Issue 1 , Winter and Spring 2016, , Pages 39-47


  This paper presents some analyses about the robust practical stability of a class of nonlinear affine systems in the presence of non-vanishing perturbations based on the passivity concept. The given analyses confirm the robust passivity property of the perturbed nonlinear systems in a certain region. ...  Read More
